Circulating water plant
A circulating water plant or circulating water system is an arrangement of flow of water in fossil-fuel power stations, chemical plants, and oil refineries. Such a system is required because various industrial process plants uses heat exchangers, and also for active fire protection measures. In chemical plants, for example in caustic soda production, water is needed in bulk for the preparation of brine. The circulating water system in any plant consists of a circulator pump, which develops an appropriate hydraulic head, and pipelines to circulate the water in the entire plant.
